I have a small mixed breed dog (min-pin/pug)and does not travel well. Displays high anxiety and is all over the place in the car while I'm driving evan under my feet. I tried using a crate but I couldn't find one to fit in my 1991 Mitsubitschi Eclipse, hense this review. My car has a back seat but good luck getting into it which is what had to do to install the barrier. The first thing I discovered was the upper straps are too short. Their designed for headrests that raise and lower on poles. My headrests are part of the complete front seat. So the upper staps would not reach around the headrest and I had to improvise by cutting the extra length from the bottom straps and tie that to the upper straps and then it would reach. That was a pain! I suggest the maker of this product add about 2 ft. of length to both sides of the upper sraps.
